I agree that zpool attach and add look similar in their syntax,
but if you attempt to add a disk to a redundant config, you'll
see an error message similar to the following:

Jokes aside, this is too easy to make a mistake with
the consequences that are
too hard to correct. Anyone disagrees?
No, and this sums up the situation nicely, in that there are two parallel paths
toward a resolution:
- make the mistake harder to make (various ideas here)
- make the

Would it be beneficial to have a command line option to zpool that
would only preview or do a dry-run through the changes, but
instead just display what the pool would look like after the operation
and leave the pool unchanged?
What about removing attach/deattach and replace it with
zpool add [-fn] 'pool' submirror 'device/mirrorname' 'new_device'
e.g.
NAMESTATE READ WRITE CKSUM
rpoolONLINE 0 0 0
mirror-01 ONLINE 0 0 0

Hi,
I wanted to add a disk to the tank pool to create a mirror. I accidentally used
zpool add … instead of zpool attach … and now the disk is added. Is there a way
to remove the disk without loosing data? Or maybe change it to mirror?
Thanks,
Martijn

Not really. Check out the zfs send and receive commands in
the ZFS Administration Guide:
http://docs.sun.com/app/docs/doc/819-5461/gbinw?a=view
Basically, you make a snapshot of every filesystem you want to backup,
then you use zfs send
